added EMS_BOILER_TAPWATER_TEMPERATURE_MAX to my_config.h, not all boilers support 90 degrees max

Browse Source 
changed tapwater detection mechanism:
  - added EMS_BOILER.wWCurFlow to be read from 0x34 messages, this gives the current amount of tapwater flowing in dl/min
  - added wWCurFlow to mqtt message
  - added wWCurFlow to telnet statistics
  changed detection from: selBurnPow and selFlowTemp to wWCurFlow
added the current servicecode as seen on thermostat and boieler display to telnet statistics and mqtt message
